本文介绍了英溪桥的加固设计和施工。该桥为单跨80米变截面悬链线双曲拱桥,是华东地区目前旧桥改造中跨径最大的一座。对拱顶巳下挠50厘米的危桥,及时采取了降低桥面标高、减少填土厚度和调整全桥自重合理分布等措施进行加固,使该桥恢复了原设计荷载。七年来通车实践证明该桥良好;加固方案合理可行;经济效益显著。对旧桥改造有一定的参考价值。
This article introduces the reinforcement design and construction of Yingxi Bridge. The bridge is a single-span 80-meter cross-section catenary double-curved arch bridge is the East China Region in the transformation of the oldest bridge in the span of the largest one. The bridge has been bent down 50 centimeters of the bridge, in time to take to reduce the elevation of the bridge deck, reducing the fill thickness and adjust the full weight of the bridge and other reasonable distribution of reinforcement, the bridge to restore the original design load. The opening of seven years to prove that the bridge is good practice; reinforcement program is reasonable and feasible; significant economic benefits. The transformation of the old bridge has a certain reference value.
